Calling Crenshaw the worst in L.A. Unified, Supt. John Deasy gets the green light to turn the landmark campus into three magnet schools.

No school has meant more to the African American community in Los Angeles than Crenshaw High. For most of its 45 years, it has been an established neighborhood hub, known for championship athletic teams and arts programs, sending graduates to top colleges.

But the Leimert Park campus has declined in recent years. Dropout rates have soared and student achievement has plummeted. L.A. Unified school Supt. John Deasy calls it one of the district's biggest disappointments.

In an effort to turn the school around, the Board of Education on Tuesday approved Deasy's drastic proposal to remake the campus into three magnets — and require teachers to reapply for their jobs.

Deasy's critics, including those at Crenshaw, were quick to complain. They say he is using an ax instead of a scalpel, that his approach would jettison talented people and abandon efforts that show some promise and deserve his support.

Rita Hall, a member of the school's first graduating class in 1969, told the board Tuesday that the school was once successful because of immense stability and support — which it lacks today. The campus, even through its struggles, is an important mainstay in the community.

"Crenshaw means family.... The board doesn't seem to recognize that there is a strong legacy and bond," Hall said. "We are very passionate about our school."

This is not the first time that Crenshaw, with an increasingly Latino student body, has been the focus of L.A. Unified's attention. Other efforts to turn around low achievement weren't successful. In 2005, the school lost its accreditation in a largely bureaucratic snafu. In 2008, the school failed to receive a state academic rating because it failed to test enough students.

Many parents are opposed to the new plan and pleaded with the board to delay the vote. Speakers blamed the district for the school's slow progress, telling the board that the campus has suffered through a parade of administrators — more than 30 principals and assistant principals over seven years, according to veteran Crenshaw teacher Alex Caputo-Pearl. The transition to magnet programs would be disruptive for students, they said.

Deasy argued that much of the sentiment expressed by parents and teachers is the reason the district is taking action to make sure student achievement becomes "dramatically and fundamentally better."

"It is a civil right for students to be able to read and do mathematics. It is a fundamental right to graduate — and it is not happening at Crenshaw," he said, adding, "Students are not learning. Students are not graduating. Students are not able to read."

Board member Marguerite Poindexter LaMotte, who represents the school and lives nearby, told the crowd to give the district a chance to transform the school into one that students could be proud of.

"We have got to change something at Crenshaw for the better," LaMotte said. "When they go to school in the morning — when I see them passing — I want them to say 'I go to Crenshaw and I'm proud to go to Crenshaw.' "

The board approved Deasy's plan unanimously with one member, Richard Vladovic, absent. After the vote, supporters began chanting "The fight is not over, we will take over!"

LaMotte quickly responded: "I'd want to know why anyone would want a child to go to a broken school."

The school, with more than 1,300 students — nearly all from low-income families — has made virtually no progress in increasing achievement in English and math. The percentage of students at grade level in English has declined slightly over four years, from 19% to 17%; in math, the figure has inched up — but only from 2% to 3%.

This year, there was an increase in Crenshaw's overall Academic Performance Index score, which includes results from all students tested. It rose from 554 to 569, which still leaves the campus among the lowest-performing in the state and, Deasy said, the worst in L.A. Unified. The school has also lost students, with many choosing other district schools or independent, publicly funded charter schools.

Deasy has authority under federal law to replace the staff at Crenshaw because of the school's poor performance, but he describes the move differently. Avoiding the term "reconstitution," which is used to describe a school that is substantially restaffed, he instead focuses on the changeover to a magnet program. But UCLA associate professor John Rogers said Deasy's move is essentially reconstitution under another guise.

The conversion echoes the strategy already employed at Westchester High, another comprehensive district high school where a majority of students are African American.

Magnet schools were designed to draw enrollment from across the district to promote integration.

District officials consider Westchester's changeover a significant improvement that allowed them to alter the culture of the school. Some Crenshaw parents, who followed events at Westchester, aren't persuaded.
